ANTECEDENTS AND CONSEQUENCES OF PHYSICAL-ACTIVITY AND EXERCISE AMONG OLDER ADULTS

The antecedents and consequences of four markers of physical activity and exercise are examined for the 6,780 baseline self-respondents to the Longitudinal Study on Aging. These dichotomous markers reflect having a level of physical activity greater than one's peers (45.8%), getting as much exercise as needed (58.9%), having a regular exercise routine (28.4%), and walking a mile or more at least once a week (29.9%). The major factors associated with engaging in these behaviors are having fewer lower body limitations, better perceived health, more non-kin social supports, not worrying about one's health, and having a sense of control over one's health. When added to traditional models predicting subsequent (over the next 6 to 8 years) mortality, nursing home placement, hospital resource consumption, and changes in functional status, the four markers of physical activity and exercise have numerous statistically and substantively significant associations, all of which involve better health outcomes.
